This paper lays out a new framework to understand the different ways that entrepreneurs unlock value in broken or dysfunctional markets. Based on the study of how successful business and social entrepreneurs are transforming markets for growth and impact in both emerging and developed economies, the framework identifies four types of “broken market” entrepreneurs, defined by their answers to the fundamental problem causing market dysfunction. The framework is intended to help System Change Entrepreneurs to identify the type of entrepreneur they need to be and provide them with guidance on the strategic choices they will face when transforming broken markets.
